Cowbit was the midnight drive, not the one where B allegedly got out of the car where Scott claimed there was an alley.
The theory seems to be that Scott murdered B on the drive where he claims she got out and ran down an alley. Then at midnight, both Scott and Sarah went on the trip to Cowbit to hide the body.
Not sure about the reference to a filling station near Spalding. Do you have the location of it so we can look on a map? And does anyone have the time of that stop?
Are there two times when Scott goes to McDonalds, because the drive in the morning seemed to end at a McDonalds, and then the early hours of the next morning also involved a trip to McDonalds?
I get muddled by the different times and drives. We need a timeline!
